Objectives: This study examined the status of children's favorite foods intake and the relationship with the policy environment based on the Special Act on Safety Control of Children's Dietary Life for suggesting a supportive policy strategy. Methods: The subjects were 4th grade students (n=1,638) in elementary school from 45 schools collected from seven areas (Seoul, Daegu, Daejeon, Gyeonggi, Chungnam, Jeonbuk, and Gyeongnam). The children participated in a self-administered questionnaire survey in class under the supervision of the teacher. The questionnaire consisted of items, such as social demographic characteristics, frequency of intake of the children's favorite foods, and policy cognition. A t-test and ANOVA were applied to explore the relationship between the frequency of children's favorite foods intake and policy cognition. The survey was implemented from August 2016 to September 2016. Results: For the boys, the frequency of 'high-calorie low nutrient foods intake' (HCLN) was significantly higher than that of the girls (p<0.01). For the children who received information on their favorite foods from the internet, the frequency of HCLN was higher than the other sources (p<0.01). The time of TV viewing and computer usage, and smartphone usage was associated with a higher frequency of HCLN, and a lower healthy favorite food intake (all p<0.001). The intake frequency of healthy favorite foods indicated a positive correlation with the policy cognition, including policy perception, usefulness, necessity and buying intention, and educational experience. Conclusions: This study showed a correlation with the frequency of children's favorite foods intake and policy. In particular, the frequency of children's healthy favorite foods intake indicated a meaningful relationship with the policy than the frequency of HCLN. This study also found that the consumption of children's healthy favorite foods was positively correlated with the educational experience. To develop a supportive policy for a good dietary environment for children, there is a need to focus on how to collaborate with multiple levels of influences, such as the national level, school level, and family.

Purpose: The purpose of this study was to identify correlations among emotional labor, servant leadership, and communication competence in hospital nurses. Methods: A self-administrated survey was conducted with a convenient sample of 210 nurses, using a structured questionnaire. The data were analyzed by descriptive statistics, t-test, ANOVA, and Pearson's correlation coefficient using SPSS/WIN 20.0 program. Results: The mean emotional labor score was $3.4{\pm}0.60$. There was very strong and negative correlation between emotional labor and servant leadership (r=-.896, p<.001). Communication competence was positively correlated with servant leadership (r=.298, p<.001) and moderately and negatively correlated with both frequency of emotional labor (r=-.166, p=.016) and the degree of attention to emotional expression (r=-.143, p=.039). Conclusion: As a strategy to reduce emotional labor of hospital nurses, the findings suggest training programs for nurses to enhance servant leadership and communication competence.

National Institute of Environmental Research (NIER) has proposed new methodology for estimating unit load in order to overcome the limitations of past unit load based on short-term and local area based data. In the case of agricultural land, however, the results presented by NIER are still limited because of various agricultural activities and farmland characteristics. In this study, liquid manure treated paddy field and organic farming upland were selected for considering agricultural diversity. Four different methods for evaluating unit load were used for comparing previous research results. The results of different methods presented various trends compared with those of existing studies. Paddy field treated liquid manure was 1.3 times higher for T-N load and 3.1 times for T-P load than conventional paddy field. Conventional upland was 4.4 times higher for T-N load and 1.8 times higher for T-P load than organic farming upland. In the case of non-conventional farmland, this study showed different values with the unit loads presented by NIER. This implies that it is necessary to review and apply the unit loads considering various agricultural conditions when establishing environmental policy and rural planning.

The purpose of this study is to verify the effects of nurses' turnover intention, Nunchi, and job stress on organizational socialization. Data were collected from 180 nurses working in hospitals in G-do. Analysis was done using t-test, ANOVA, Pearson correlation coefficient, and Multiple regression with IBM SPSS WIN/21.0. Organizational socialization was inversely correlated to turnover intention (r=-.52, p<.001), job stress (r=-.31, p<.001), and was positively correlated to Nunchi (r=.33, p<.001). The most influential factor on the subjects' organizational socialization was turnover intention (β=-.37, p<.001), Nunchi (β=.26, p<.001), job stress (β=-.24, p<.001), deployment to the desired department (β =.19, p=.001), Age 30 years or younger (β=-.14, p=.012), and Working department-OR (β=.11, p=.050). The explanatory power was 47.0% (F=25.59, p<.001). Therefore, a organizational socialization enhancement program is needed to reduce turnover intention and job stress. Also, age and desired depertment need to be taken into account when assigning departments.

A combination of the submerged membrane activated-sludge bioreactor(SMABR) equipped with non-woven fabric filter and oyster-zeolite (OZ) packed-bed adsorption column was studied to evaluate the advanced tertiary treatment of nitrogen and phosphorous. The non-woven filter module was submerged in the MBR and aeration was operated intermittently for an optimal wastewater treatment performance. Artificial wastewater with $COD_{Cr}$ of 220 mg/L, total nitrogen (T-N) of 45 mg/L, and total phosphorous (T-P) of 6 mg/L was used in this study. MLSS was maintained about $4,000\;{\sim}\;5,000\;mg/L$ throughout the experiments. The experiments were performed for 100-day with periodic non-woven filter washing. The results showed that $COD_{Cr}$ could be effectively removed in SMABR alone with over 94% removal efficiency. However, T-N and T-P removal efficiency was slightly lower than expected with SMABR alone. The permeate from SMABR was then passed through the OZ column for tertiary nutrients removal. The final effluent analysis confirmed that nutrients could be additionally removed resulting in over 87% and 46% removal efficiencies for T-N and T-P, respectively. The results of this study suggest that the waste oyster-shell can be effectively reclaimed as an adsorbent in advanced tertiary wastewater treatment processes in combination with SMABR equipped with non-woven fabric filter.

This paper contains the following errors. 1. "$I_{\{x>D\}}{\lambda}dt_{p0}(t)s(x)$" should be added to the right hand side of (2.3). 2. "$I_{\{x>D\}}{\lambda}_{p0}(t)s(x)$" should be added to the right hand side of (2.6). 3. "$I_{\{x>D\}}{\lambda}_{p0}s(x)$" should be added to the right hand side of (2.9). 4. In Theorem 2.3 and its proof, "${\lambda}{\int}_{0}^{D}f(y)s(x-y)dy$" appears three times (including one in (2.20)). To each of these, "${\lambda}_{po}s(x)$" should be added. 5. In Remark 2.5, "${\lambda}dt_{p0}/s(x)dx" should be added to "${\int}_{0}^{D}{\lambda}dt\;s(x-y)dxf(y)dy$". As a result of these corrections, a simpler proof of Theorem 2.3 becomes available. Substituting (2.18), (2.21), (2.22) into the left hand side of (2.20) and comparing the result with (2.10), we have the right hand side of (2.20).
